Abstract卫星激光测距是研究天文地球动力学,大气动力学,地球物理学等众多学科的一个技术手段。 本文研究不带后向反射器的漫反射卫星激光测距。主要是从理论和实验这两方面出发,预测当用多大的激光出射能量时能探测到多远距离的卫星,当然这也与用的激光器光束参数有关.。 文章先从传统激光测距回波光电子数公式开始,提出了从理论推导到实验方法,实际预测的漫反射激光测距方法。主要做的工作有: 1 结合激光测距回波光电子数公式和引入的一个参数,推出了漫反射激光卫星测距公式和地靶实验公式。 2 利用我们小组库德房的实验设备做了实验室实验,验证其中两个参数,并且根据实验数据来校正理论推导假设不足。 3 编写了实验处理程序,并且对实验数据用软件进行了分析和拟合。 我做的工作在理论和实验上都还只是个方案,在理论推导和实验中所做的一些简化也不尽入人意,相信在随着实验设备和后续工作的进行,漫反射卫星激光测距会变为现实。
Other AbstractSatellite Laser Ranging (SLR) is a technical method to study many subjects such as geodynamics, atmospheric dynamics and geophysics. The aim of this paper is to try to observe the satellite with no retroreflector based on SLR. Based mainly on theories and experiments, we forecast the dependence of the distance of the satellite that can be observed on the power of the laser. Of course, the dependence is related to the beam parameter of the laser. According to the conventional laser ranging, the theoretical derivation, experimental methods and the forecasted method of Diffuse Reflection Laser Ranging are presented in this paper. Main items of the work are listed as below: 1. Combining SLR eqaution and parameter, a new formula of Diffuse Reflection Satellite Laser Ranging is deduced. The parameters in the formula are also deduced in detail. 2. Using our experimentation equipments, laboratory experiments are made and two parameters thereinto are testified. According to experimentation data, theories are revised and hypotheses and insufficiencies are presented. 3. The experiment computer data—processing program is writed and experimentation data are analysed and fitted using the program. Taking theories and experiments into account, my work is only a scheme. Simplifies made in the theoretical derivation and experiments are not entirely satisfying. We think that Diffuse Reflection Satellite Laser Ranging will become a realy with the development of experimentation equipments and following work.
